Chrysomya megacephala (Fabricius, 1794) (Diptera, Calliphoridae) acts as a vector of many disease-causing pathogens. It causes myiasis in human beings and other living vertebrates. In the present study, the effect of a juvenile hormone analog (JHA), fenoxycarb, was evaluated on pupal-adult transformation by exposing pupae (0 and 1-day-old) of blowfly. Read More

is a recently identified genus of bacteria that has been isolated from the digestive tract of multiple flies associated with decomposing tissue. Species within this genus are rarely implicated in human disease, and less than 10 cases worldwide have been documented in the literature. Although there have been several documented cases of bacteremia in the United States (with one previous case in Louisville, KY), this case represents the first documented case of bacteremia in the United States.

The family Calliphoridae is a group of heterogenous calyptrate flies with a worldwide distribution including species of ecological, veterinary, medical, and forensic importance. Notorious for their parasitic habits, the larvae of many blowflies are characterised - like some other dipteran larvae - by their ability to develop in animal flesh. When parasitism affects a living host, it is termed "myiasis". Read More

In this study, cloacal myiasis caused by dipterans of Lucilia genus was found in a rooster (Gallus gallus domesticus) and two Harris's hawks (Parabuteo unicinctus) from Peru. Larval dipteran were collected and preserved in ethanol. Morphological analysis indicated two species: Lucilia sericata in the rooster and in one Harris's hawk, and Lucilia cuprina in the other Harris's hawk. Read More

Enteral myiasis or intestinal myiasis is acquired by ingesting food or water contaminated with dipteran fly eggs or larvae. Here, we describe a patient with intestinal myiasis presenting with acute dysentery caused by the larva of Hermetia illucens. The larva was identified morphologically, and its species confirmed through molecular analysis using polymerase chain reaction and sequencing based on mitochondrial cytochrome c oxidase subunit I gene (COI).

Suction aspiration, which has not yet been described in the treatment for myiasis in the periorbital and facial regions, was used to achieve rapid resolution of maggot burden in a 78-year-old patient who presented with a large ulcerated squamous cell carcinoma of the face. This technique also facilitates submission of parasite samples for further analysis. Suction aspiration had no complications, such as significant residual ruptured maggots in the wound or eye injury.

Background: The rehabilitation of injured wildlife and their subsequent release into the wild is a humane act as well as important in wildlife conservation. However, little is known about the animals' fate after release. Therefore, to address these uncertainties, it is essential to adequately describe how the injured animals were treated and managed before releasing into the wild; moreover, post-release monitoring should also be performed.

Synthesiomyia nudiseta (van der Wulp, 1883) is a synanthropic muscid found in tropical and subtropical zones around the world. The larvae of this species are a secondary agent of myiasis with necrophagous habits and play an important role in forensic entomology, as they are used as an indicator of post-mortem interval. Adults can be considered vectors of etiological agents such as Escherichia coli and Shigella dysenteriae. Read More

Myiasis is a rare disease caused by infestation of tissue by larvae of flies. Oral myiasis is still rare and unique owing to the fact that the oral cavity rarely provides a necessary habitat for a larval life cycle. We discuss the definition, etiology, predisposing factors, classification, and management of myiasis. Read More
